Last night I received goal prompt for
Frozen frenzy mania download got to level 15 than 35 received six gems for download that 3 than another 3. I play on android and iPad when I opened iPad app I received more gems plus if I served coffee I got free ice cream truck display so if you play on ios make sure to do goal at least till level 35.
When you open android it's on sale for 40 gems though.
